1. 1. Statistical and machine learning methods to analyze large-scale mass spectrometry data

   Författare :Matthew The; Lukas Käll; Oliver Kohlbacher; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry - LC-MS MS; statistical analysis; data processing and analysis; protein inference; large-scale studies; simulation; protein quantification; clustering; machine learning; Bayesian statistics; Bioteknologi; Biotechnology;

   Sammanfattning : Modern biology is faced with vast amounts of data that contain valuable information yet to be extracted. Proteomics, the study of proteins, has repositories with thousands of mass spectrometry experiments. These data gold mines could further our knowledge of proteins as the main actors in cell processes and signaling. LÄS MER

3. 2. Statistical and machine learning methods to analyze large-scale mass spectrometry data

   Författare :Matthew The; Lukas Käll; Fredrik Levander; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry - LC-MS MS; statistical analysis; data processing and analysis; protein inference; large-scale studies; simulation; Bioteknologi; Biotechnology;

   Sammanfattning : As in many other fields, biology is faced with enormous amounts ofdata that contains valuable information that is yet to be extracted. The field of proteomics, the study of proteins, has the luxury of having large repositories containing data from tandem mass-spectrometry experiments, readily accessible for everyone who is interested.

4. 3. Time-domain Reconstruction Methods for Ultrasonic Array Imaging : A Statistical Approach

   Författare :Fredrik Lingvall; Tadeusz Stepinski; Karl-Jörg Langenberg; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Ultrasonic array imaging; synthetic aperture imaging; maximum a posteriori estimation; linear minimum mean squared error estimation; SAFT; Bayesian image reconstruction; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

   Sammanfattning : This thesis is concerned with reconstruction techniques for ultrasonic array imaging based on a statistical approach. The reconstruction problem is posed as the estimation of an image consisting of scattering strengths. LÄS MER

5. 4. Biomass gasification in fluidized bed gasifiers : Modeling and simulation

   Författare :Guilnaz Mirmoshtaghi; Erik Dahlquist; Jan Brandin; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed.

7. 5. Variation Control in Virtual Product Realization - A Statistical Approach

   Författare :Kristina Wärmefjord; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; quality control; contact modeling; Variation simulation; welding simulation; spot welding sequence; inspection point reduction; fixture repeatability;

   Sammanfattning : All manufacturing processes are afflicted by variation, which leads to products that may not fulfill assembly, functional or esthetical requirements. The variation in the final product originates from variation in individual parts and assembly processes. LÄS MER
